SPECIFICATION forming part of Letters Patent No. 592,280, dated October26, 1897.

Application filed November 23, 1896. Serial No. 613,118. (No model.)

To all whom it may concern:

Be it known that I, HENRY F. CRANDALL, of Milwaukee, in the county ofMilwaukee and State of WVisconsin, have invented certain new and usefulImprovements in Harve'ster- Elevatorsj and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification and are designed to show my improvementsin connectionwiththose parts of an [appropriate harvester, illustra-'tion of which is needed toconvey a proper understanding of a suitableapplicationof my invention.

My invention is designed to be "applicableto that class of harvesters bywhich the grain" is taken from a platform-carrier and elevated anddelivered to a binder located upon the stubbleward side of thedrive-wheel. Its object is to provide a more positive deliveryof thegrain to the binding mechanism, to prevent the accumulation of grainbetween the upper end of the receiving-deck and the adjacentelevator-roller, and to reduce the height of an elevator-harvester asmuch as possible.

In the drawings, Figure 1 is a plan View illustrating my invention, thesection being from left to right across the delivery end of theelevator-carriers and that portion of the binder-deck reaching acrossthe drive-wheel, the deflector-sheet, the pipe-support for the binderattachment,and a portion of the breast;

plate, showing the manner of connecting the breast-plate to thedeflector-sheet and also the connection between the deflector-sheet andthe floating'frame. The rollers areshown: broken, also thedeflector-sheet, and for the purpose of better illustrating myimprovements I-have omitted the canvas apron. Fig.

2 is a sectional elevation somewhat in the nature of a diagram, thesection being from right to left through the elevator and the dischargeside of the platform-conveyer at one side and the receiving side of thebinderdeck at the other side of the driving-wheel, which appears inelevation, the same being shown without grain in the elevator and someelevation similar to Fig. 2 and designed to showthe actionof the grainupon the fioating supplemental carrier, it being shown as forced'upwardaround its pivotal connection with the elevator-frame, carrying thegrainward side of the deflector with it and providing a storagereceptacle for the accumulating grain when held back from the bindingmechanism by the action of the needle.

1 is the drive-wheel 2, the platform-carrier roller at the dischargeside. 3 is the elevator side sheathing; 4, the shifting binder-deck; 5,the upper elevator-apron; 6, the lower elevator-apron; 7 and 7respectively, the lower and upper rollers of the lower apron; 8 and 8',respectively, the lower and upper rollers of the upper apron. 9 is asupplemental lower roller of the upper apron. 'f It will be understoodthat the terms upper and lower as applied tothese rollers correspond tothe discharge and receiving side as applied to carriers. 1

10 is a fixed deck located above the' d'rivewheel and extends from thegrainward side thereof to the movable binder deck upon 'the stubblewardside of the machine.

11 is the needle; 12, the breast-plate; 13,

:the tier-cam; 14 and 15, respectively, the receivingand dischargingrollersof thesupplemental transverse conveying-apron;'16, the deflectorsheet; 18, thefpip'e support on binder; 17, the supplementalcarrier-apron; 19, sliding and pivotal connection between breast-plate12 and deflector-sheet 16; 20 and 20, short pivotal links connecting thegrainward edge of the deflector-sheet to the stubbleward end of thetransverse floating frame carrying the supplemental apronand rollers; 21and 21, swivel journal-box forming bearings for the journals of roller15 in swinging frame-pieces 22 and 22. These frame-pieces are shown asbeing made of sheet metal and having the stiffening-pieces 23 and 23,carrying the swivel-boxes 21 and 21, riveted to them, and are pivoted atthe receiving-roller journals. This receiving-roller is journaled in anyconvenient manner (not specifically shown) at the front and rear of theelevator in the same manner as the other rollers and is located nearlyin a vertical line above the upper roller of the upper elevator-apron.The upper roller of the upper elevator-apron is located at a point belowand grainward of the upper roller of the lower elevator-apron. The upperroller of the lower elevator-apron is located at a point grainward ofthe drivewheel and at a height to bring the upper part of its peripherya little below the plane of the fixed binder-deck 10. This fixedbinder-deck is preferably made of sheet metal and has its grainward siderolled in tube formation, affording required stiffness and presenting arounded surface to meet the flow of grain and contiguous movingearrier,its lower side overlapping the movable binder-deek 4. and heldin position by clips shown at 24, Figs. 2 and 5.

lVith my improvements in operation the grain is received from theplatform-carrier by the elevator carrier-aprons, and between them it iscarried to a height corresponding with the plane of the fixedbinder-deck, and there it meets the action of the supplemental floatingor swinging carrier and is positively forced in practically a horizontalplane across the opening between the fixed deck and the upper roller ofthe lower elevator-apron, and thence across this deck to a point withinthe compass of the packing and binding mechanism. As the volume of grainincreases the supplemental eonveyer is carried upward around its pivot,as shown by dotted lines in Fig. 2, and as it diminishes the conveyorswings down until the slats on the apron come in moving contact with therounded receiving end of the fixed deck, and I prefer to have it droplow enough to allow the surface of the apron to touch said rounded endwhen taut and to bend up to allow the slats to pass the edge of thedeck. This action effectually prevents any accumulation of grain betweenthe deck and the adjacent elevator-roller, as the action of thisfloating carrier is as effective with a very small quantity of grain aswith a larger, allowing none to accumulate.

In harvesting grain it frequently happens that the butts will be filledwith a short growth of grass or weeds and are heavier and bulkier, andthe carrier, pressing heavier on this portion, will advance it faster,or, again, other conditions are present and the heads are bulkier andthey will get in ad vance of the butts. To meet these conditions,I havemade provision for an oscillatory or vibrating movement of mysupplemental carrier, as shown in Fig. 1. The de- Hector-sheet issupported by the rod 19, passing freely through an eye at the grainwardend of the breast-plate 12, and the grainward edge of thedeflector-sheet is pivotally connected by the links 20 and 20 to therising-and-falling end of the frame-pieces 22 an 22', and thejournal-bearings 21 and 21' being free to accommodate themselves to anymovement in this respect by reason of their swivel connections with theend of the frame of the supplemental carrier it follows that thedelivery end of the floating supplemental carrier is free to swing orvibrate to a limited extent upon its supporting-point, as shown bydotted lines in Fig. 4.

Any of the usual modes of driving the receiving-roller of thesupplemental carrier may be employed. I have shown a sprocketwheel 25attached to the lengthened journaled end, from which flexible connectionis made to any of the driving mechanism in some one of the well-knownways.

It is when loose grain is allowed to accu' mulate at the delivery end ofthe elevatoraprons and lying loosely across the opening between the deckand e1evator-roller that it is drawn down between them. A number ofdevices have been used in trying to prevent this. All so far have beenineifeetive in preventing the evil, but with my improved supplementalapron, rising and falling with the stream of grain and so arranged as tosweep the last single straw across the opening, the trouble is entirelyovercome.

I am aware that I am not the first to use asupplementalconducting-carrier moving in practically a horizontal plane above thedelivery end of the elevator-carriers, the same having been in usebefore; but I have no knowledge of said supplemental conductingcarrierbeing pivoted above and grainward of the upper roller of the lowerelevator-apron, with its stubbleward or delivery roller overhanging thebinder-deek and being free to ride and fall or float upon the stream ofgrain.

Vhat I claim, and desire to secure by Letters Patent, is-

1. In a harvestirig-machine, the combina tion with the elevator andbinder, of a vertically-swinging auxiliary carrier, pivotally connectedat its grainward end with the elevator-frame and extending therefromtransversely over the upper end of the elevator, and a deflector-sheetpivotally connected with the frame portion of the binder and with theverticallymovable delivery end of the auxiliary carrier, substantiallyas shown and specified.
